Fitting the rechargeable battery pack
Remove the battery pack housing and fit the rechargeable pack, complete with batteries, onto the transmitter.
Charging rechargeable batteries
The rechargeable pack can be charged with the pack fitted to, or removed from, the transmitter.
Charging options
Caution. If the batteries are being recharged from a vehicle cigarette lighter and the vehicle is being driven,
rechargeable battery packs must not be recharged whilst attached to transmitter or receiver units.
Caution. When charging batteries from a battery charger, always ensure that the battery charger is suitable for
the batteries being charged.
Note: When charging batteries for the first time they should be charged for 16 hours regardless of any indicated
charge state. For subsequent charges the batteries can be removed from charge once the green light is
illuminated.
Under normal charging conditions, the battery charge status indicator LED illuminates and is coloured red. Once
the batteries have finished charging the LED colour changes to green to indicate that charging is complete.
If the battery pack is completely discharged, or has been left in hot ambient temperatures, and the batteries
have become hot, the LED will flash red/green as soon as the battery charger is plugged in, and may continue
to flash for sometime. In the case of a hot battery pack, the LED will turn red once the battery pack has cooled
down, indicating that the batteries are charging normally. The LED will turn green once charging is finished.
If the LED is flashing red/green because the batteries are completely discharged, the LED will continue to flash
red/green and trickle charge the batteries until they have reached a pre-determined charge level. The LED will then
turn red, indicating that the batteries are charging normally. The LED will turn green once charging is finished.
The battery pack can be safely removed from charge at any stage in the charging cycle without affecting the
battery life. However, the batteries will only be partially charged.
The rechargeable batteries are not replaceable. If a fault occurs with the rechargeable battery pack, it must be
returned to Radiodetection for repair.
The rechargeable battery pack can be recharged via a vehicle
cigarette lighter of a stationary vehicle, or from a mains power
adaptor (contact Radiodetection for details). To charge the battery
pack, lift the battery pack connector cover and plug the charger lead
into the transmitter connector. Plug the other end into the vehicle
cigarette lighter socket or plug the mains power adaptor into an
appropriate power supply and switch the power supply on. It takes
approximately 8 hours to fully charge the batteries if the transmitter
is switched off during charging.
Note: It is normal for the battery pack to become warm during charging.
